I was working on the avionics mounts and saw a potential chafe hazard for the bus wires that run close to where the new mount is located.
I decided to cut a piece and place some 1/16 nylon sheet material as a barrier between the nutplates and the bus wires that run in that area. I made a couple aluminum spacers to hold the riveted portion a little higher and riveted the nylon with an aluminum washer for sandwiching the nylon to the spacer.
The nylon barrier makes me feel better about the bus wires being protected.
